Nasty8

Hey all , this is my first post here so bare with me . I bought an Rx8 about 3 months ago and judging from the mechanic reports the guy who had it from brand new drove it prety hard.
I find now when the car is in idle with the clutch engaged it sounds normal , once i take my foot off the clutch a grinding noise occurs . Has anyone had this simlar problem before???

If this is with the gear in neutral and feet off clutch, a whirring sound from the tranny is normal.
